Abstract BackgroundTyphoid fever and Helicobacter pylori infection increases the secretion of gastric acid that leads to gastric carcinoma. In this research, we have tried to investigate the prevalence of typhoid and H. pylori in Faisalabad, Pakistan.MethodIn the present study, we collected the laboratory reports from different hospital of Faisalabad, Punjab, Pakistan. Statistical Package for Social Sciences (SPSS) (Chicago, IL), version 25 was used for data processing.ResultOur results demonstrated that H. pylori was most frequent in male at the age of 41–50-year-old and typhoid in female having 21-30 age.ConclusionConclusively, mostly female in typhoid and male in H. pylori were infected. People having 21-30 age were greatly infected by typhoid. The patients owing the 41-50 age were more susceptible for H. pylori infections. By comparing the co-infection rate, we found that typhoid is most common in over all age group than H. pylori.

Background: Presence of H. pylori infection was found associated with peptic perforation and gastric carcinoma. Present study tried to estimate the prevalence of H. pylori infection in those patients and to find out the correlates of H. pylori infection.Methods: After matching the inclusion and exclusion criteria, all cases of diagnosed peptic perforation and gastric carcinoma were taken for this prospective, single center, observational study.Results: Among the study population, gastric carcinoma was found in higher age group; whereas peptic perforation was found in lower age group; male and female ratio was 2:1 in both groups of patient. Laborer and housewives were mostly affected in both cases. Gastric carcinoma was more prevalent in urban residents, opposite was seen in peptic perforation. Most patients in two groups had no previous co-morbid condition. Use of NSAIDs was found in high frequency in both groups. Most of the patients were chronic alcoholic and chronic smoker, and most of them had history of taking spicy foods more than twice in a week.Conclusions: H. pylori infection was found in high frequency in both group of patients, and it was higher in peptic perforation. The study establishes the association of H. pylori with the gastric carcinoma and peptic perforation.

Introduction: Helicobacter pylori (H. pylori) is a bacterium causing chronic gastric infection and may cause gastric cancer. It was necessary to see the trend of infection, especially in symptomatic patients. This retrospective descriptive study was aimed to describe the characteristics of H. pylori infection in Bhutanese patients referred for an endoscopy to the National Referral Hospital, Thimphu. Methods: The sample of the study was randomized 380 medical records of the patients who underwent upper gastrointestinal endoscopy and Rapid Urea Test for symptomatic dyspepsia and peptic ulcer. Data was collected using a survey form designed by the researchers. Data analysis was done using descriptive statistics and either Chi-square or Fisher’s exact test. Results: The prevalence of H. pylori infection was very high (76.6%). The mean age of the infection was 42 with a range from 15 to 84 years. The highest prevalence of infection was observed in the age group 20-29 years (82.7%) and lowest in the oldest age group 70-84 years (66.7%). The analysis showed no significant difference in infection amongst age groups, gender, and endoscopic findings to the positive results at 5% significant level except for monthly prevalence (p<0.001). Gastritis was the commonest endoscopy finding (153/380) and gastro-duodenitis had the highest positivity rate (88.9%). Conclusion: The prevalence of infection was relatively high compared with previous studies. Young and middle-aged adults had a high prevalence and this group needs to be given priority for screening and eradication treatment considering limited resources to prevent associated gastric cancer in Bhutan.

Helicobacter pylori (H. pylori) infection promotes the metastasis of gastric carcinoma cells by modulating signal transduction pathways that regulate cell proliferation, motility, and invasion. Astaxanthin (ASTX), a xanthophyll carotenoid, is known to inhibit cancer cell migration and invasion, however the mechanism of action of ASTX in H. pylori-infected gastric epithelial cells is not well understood. To gain insight into this process, we carried out a comparative RNA sequencing (RNA-Seq) analysis of human gastric cancer AGS (adenocarcinoma gastric) cells as a function of H. pylori infection and ASTX administration. The results were used to identify genes that are differently expressed in response to H. pylori and ASTX. Gene ontology (GO) analysis identified differentially expressed genes (DEGs) to be associated with cell cytoskeleton remodeling, motility, and/or migration. Among the 20 genes identified, those encoding c-MET, PI3KC2, PLCγ1, Cdc42, and ROCK1 were selected for verification by real-time PCR analysis. The verified genes were mapped, using signaling networks contained in the KEGG database, to create a signaling pathway through which ASTX might mitigate the effects of H. pylori-infection. We propose that H. pylori-induced upregulation of the upstream regulator c-MET, and hence, its downstream targets Cdc42 and ROCK1, is suppressed by ASTX. ASTX is also suggested to counteract H. pylori-induced activation of PI3K and PLCγ. In conclusion, ASTX can suppress H. pylori-induced gastric cancer progression by inhibiting cytoskeleton reorganization and reducing cell motility through downregulation of c-MET, EGFR, PI3KC2, PLCγ1, Cdc42, and ROCK1.

Helicobacter pylori is a pathogen that is considered to cause several gastric disorders such as chronic gastritis, peptic ulcer and even gastric carcinoma. The current therapeutic regimens mainly constitute of a combination of several antimicrobial agents and proton pump inhibitors. However, the prevalence of antibiotic resistance has been significantly lowering the cure rates over the years. Nanocarriers possess unique strengths in this regard owing to the fact that they can protect the drugs (such as antibiotics) from the harsh environment in the stomach, penetrate the mucosal barrier and deliver drugs to the desired site. In this review we summarized recent studies of different antibacterial agents orally delivered by nanosized carriers for the eradication of H. pylori.

SUMMARY BACKGROUND: There is evidence of detection of Helicobacter pylori (H. pylori) in the stool of newborns and in the yeast that colonizes the oral cavity of this age group. However, there is a lack of research to confirm it. This study proposes to determine the existence of the bacteria at an early age, specifically in newborns. OBJECTIVE: To identify intracellular H. pylori in oral yeasts and to detect antigens of the bacteria in newborn stools. METHODOLOGY: Cross-sectional and descriptive study. Samples were obtained from infants (oral swab and meconium). Identification of yeast species was performed using the following techniques: CHROMagar Candida, Germinal Tube Test and API Candida Identification System, then the yeasts were observed by light microscopy and fluorescence. Detection of H. pylori antigen in meconium and PCR were performed to amplify specific genes of the bacterium (rRNA16S, cagA, vacA s1a, vacA s1b, vacA s2, vacA m1, vacA m2 and dupA). RESULTS: Intracellular H. pylori was detected in yeast of the species Candida glabrata (C. glabrata) isolated from an oral swab of a newborn. CONCLUSION: The results of this study evidenced the existence of intracellular H. pylori in newborns.

SUMMARYPatients (454) referred for gastroscopy to the General Hospital of Athens were examined to determine (1) if non-secretors were over-represented among patients with ulcers and (2) is there was an association with ABO blood group or secretor status and carriage ofHelicobacter pylori.Compared with the local population, among patients with either gastric ulcer (51) or duodenal ulcer (96) there was a significant increase in the proportion of those who were blood group O (P< 0·025); however, there were no significant differences in the proportions of non-secretors.H. pyloriwas identified in 62 % of the 454 patients: 59·5 % of those without evidence of ulcers; 62·5 % of those with gastric ulcer; 88% of those with duodenal ulcer (P< 0·0005). These bacteria were cultured more often and in higher numbers from patients with duodenal ulcer (P< 0·025). There was no association between ABO blood group and prevalence ofH. pylori. The prevalence ofH. pyloriamong non-secretors with gastric ulcer (12·5%) was significantly lower than that for non-secretors with duodenal ulcer (100%) (P< 0·0005). This was not observed for secretors.

BACKGROUNDOmeprazole has a greater intragastric pH elevating effect in Helicobacter pylori positive than negative subjects. Ammonia production byH pylori has been suggested as a probable mechanism.AIMSTo assess the effect ofH pylori status on gastric acid secretion during omeprazole treatment, and to examine the possible role of ammonia neutralisation of intragastric acid in increased omeprazole efficacy in infected subjects.METHODSTwentyH pylori positive and 12H pylori negative healthy volunteers were examined before and six to eight weeks after commencing omeprazole 40 mg/day. On both occasions plasma gastrin and acid output were measured basally and in response to increasing doses of gastrin 17 (G-17). Gastric juice ammonium concentrations were also measured.RESULTSPrior to omeprazole, measurements were similar in the H pyloripositive and negative subjects. During omeprazole, median basal intragastric pH was higher in the H pyloripositive (7.95) versus negative (3.75) subjects (p<0.002). During omeprazole basal, submaximal (180 pmol/kg/h G-17), and maximal acid outputs (800 pmol/kg/h G-17) were lower in H pylori positive subjects (0.0, 3.6, 6.0 mmol/h respectively) versus negative subjects (0.3, 14.2, 18.6 mmol/h) (p<0.03 for each). This effect was not explained by neutralisation by ammonia.CONCLUSIONThe presence ofH pylori infection leads to a more profound suppression of acid secretion during omeprazole treatment. The effect cannot be explained by neutralisation of intragastric acid by bacterial ammonia production and its precise mechanism has to be explained.

Introduction: Treatment of Helicobacter pylori has various side effects like antibiotic resistance. The purpose of this study was to evaluate the effects of cinnamon extract on complications of treatment and eradication of H. pylori in infected people. Methods: In this randomized clinical trial, a total of 98 eligible healthy and H. pylori-infected patients approved by esophageal endoscopy were selected. The cinnamon group received multi-drug treatment including clarithromycin, amoxicillin and pantoprazole as well as a cinnamon extract capsule. The control group received multi-drug treatment and a 40 mg starch capsule. In order to analyze the cinnamon extract efficacy, the urea breath test (UBT) was performed 3 months after the start of treatment. Clinical symptoms were evaluated by a questionnaire at the beginning (day of 0), 7 days and 14 days after starting treatment. Results: The clinical symptoms such as nausea, vomiting, diarrhea, constipation, blurred vision, headache, metallic flavor, epigastric pain, burp, and appetite were significantly reduced in the cinnamon group (P < 0.05). The odds ratio exhibited a higher eradication rate of H. pylori in the cinnamon group (73.47% in the cinnamon group compared to 53.06% in the control group) (P = 0.036). Conclusion: Cinnamon as assisted therapy is able to alleviate the disease and reduce the complications of H. pylori treatment.
